I have been buying Drive-in DVD collections and out of print DVDs. It is the general retoric that these films are in the PD, (some of which I have checked out at broadcast suppliers of Public domain content). I would like to upload new content, but; question that this may be unwelcome.
Be careful with some of those titles. BCI had been putting out some of the Crown International Pictures films which are all copyrighted. Mill Creek now has an exclusive license for those same Crown International Pictures. Also be careful with other titles put out by BCI and Mill Creek. There are some titles which contain valid copyright notices while others that are protected by international copyright(GATT).
